Let's get started, and demystify the digital video world together!

Core Digital Video Advertising Terminology

Alright, let's kick things off with some core terms that you'll encounter all the time. Understanding these will give you a solid foundation for everything else. We are going to explore the landscape of digital video advertising. I'll make sure to break down the language that might be confusing to help you understand the core terminology. This section is going to be your best friend when you start to interact with the world of digital video.

Ad Server: This is the workhorse of the operation. An ad server is like the traffic controller for your video ads. It stores, delivers, and tracks your ads. Think of it as the central hub where all the magic happens. Every time a video ad appears on a website or app, it's the ad server that makes it happen. The ad server is also the main source of the measurement. You can track performance metrics such as impressions, clicks, and conversions. Without an ad server, your video ads would never see the light of day. They are used to help determine which ad to show, when to show the ad, and to whom the ad will be shown.
Ad Unit: An ad unit refers to a specific place on a website or app where a video ad can be displayed. It's like a designated slot, and publishers define these units. The ad unit's characteristics will impact the type of ad that can be displayed. You can determine the size of the ad, the placement, and the ad format, so you will want to get familiar with ad units. If you are a publisher, this is how you can determine the ad size and ad type that you are going to show. If you are an advertiser, this is where you can begin to consider the context of where the ad is shown and to who the ad is shown. You can also begin to determine if the ad unit is the right fit. This is a very essential piece of the puzzle.
Companion Ad: Imagine your video ad has a sidekick. That's a companion ad! It's a smaller ad, typically a banner, that appears alongside your video ad. It's there to provide additional information, reinforce your message, or encourage viewers to click through. You often see it at the top or bottom of the player, or sometimes beside the video. It offers a great opportunity for extra branding and calls to action.
Creative: This is the actual video ad itself – the content, the visuals, the sound, the whole shebang. The creative is what the audience sees and interacts with. It includes the video, any accompanying text, and the call to action. The creative is a critical element, because it's what influences the user's perception of your brand. Getting it right is key. You'll want to focus on this, and the creative should be tailored to the specific ad unit and target audience.
Impression: An impression is simply counted every time your video ad is displayed. It's the most basic metric and provides an idea of the ad's reach. Think of it as a view. However, an impression doesn't necessarily mean the user watched the entire ad. It just means the ad was shown.

Diving Deeper: Ad Formats and Specifications

Now, let's explore the various formats your video ads can take. It's like choosing the right outfit for the occasion. Different formats are suitable for different platforms and objectives. Each format has its own set of technical specifications, so knowing the specifics can greatly affect the outcome of your campaigns.

Pre-roll: These are the ads that play before the main video content. Pre-roll ads are a staple in online video advertising. They are typically short and attention-grabbing. This is when the viewers are usually paying the most attention, since the video is about to begin. They offer excellent reach, but they can sometimes be annoying, which can potentially lead to some negative sentiment towards the brand. The length of the pre-roll ad and the relevance to the content can play a part in its success. Make it count, because this is an important format.
Mid-roll: As you might have guessed, these ads appear during the main video content. Mid-roll ads are more common in longer videos. They offer an opportunity to reach viewers who are already engaged. The placement and length of the ad are crucial, because you don't want to disrupt the viewing experience too much. You want to avoid placing mid-roll ads in places that feel unnatural, or where the viewer is not likely to keep watching.
Post-roll: These ads play after the main video content. Post-roll ads are useful for delivering a final message, or a call to action. They may have a lower completion rate, but they can still be effective. This is great for those who made it through the content, and you still have their attention. Think of this as the end credits of a movie.
Overlay Ads: These ads appear as a layer on top of the video. They are a great way to make sure the user sees the ad without taking up too much of the screen. They can be static or interactive. Overlay ads offer a less intrusive way to promote your message, but the user is able to dismiss it, if it's too distracting. The success of overlay ads depends on a combination of the user experience and ad relevance.
Outstream Ads: These are video ads that play outside of a video player. This means they can be shown in articles, within content feeds, and on other places that are not traditionally used for video content. They provide new opportunities for advertisers to reach audiences, especially on mobile devices. Outstream ads are usually designed to be engaging, and to seamlessly integrate into the user's experience.

Targeting and Measurement: Key Strategies

Now, let's talk about targeting and measurement, which are crucial for success in digital video. Targeting ensures your ads reach the right audience, and measurement helps you understand what's working. These are two critical components that can make or break a digital video advertising campaign.

Targeting: Targeting is all about reaching the right people. You can target users based on demographics (age, gender, location), interests, behaviors, and even the content they're consuming. Targeting allows advertisers to focus their budgets, and to increase their chances of success. With the right targeting, the likelihood of a higher engagement is possible.
View-Through Rate (VTR): This metric measures the percentage of viewers who watched your entire video ad. It's a crucial indicator of engagement. A high VTR suggests that your ad is resonating with your audience. If you have a low VTR, that is a signal that something is off, and that you will need to revisit the creative or targeting to improve results.
Click-Through Rate (CTR): This metric tells you the percentage of viewers who clicked on your ad. It's a good measure of the ad's ability to drive action. A high CTR indicates that your ad is engaging and effectively encourages viewers to take the desired action.
Cost Per Mille (CPM): CPM is the cost per 1,000 impressions. It's a common pricing model in digital advertising. This allows advertisers to pay for every 1,000 times that their ad is shown.
Cost Per View (CPV): CPV is the cost per view. This means you only pay when someone watches your video ad. This can be a more efficient way to spend your budget, because you are only paying for views. This also allows you to focus on the overall experience, and to make it as engaging as possible.
Video Completion Rate: This is the percentage of viewers who watched your video ad to completion. This is a very important metric, because it helps determine the overall quality of your ad campaign. A high completion rate means that the audience enjoys your content.
Brand Lift: This is the increase in brand awareness or favorability resulting from your ad campaign. This is something that is more difficult to measure, and relies on surveys and data. It provides insights into the impact of your ads on your brand.

Advanced IAB Digital Video Concepts

Let's move on to some more advanced concepts that you might encounter. These are important for anyone looking to get more familiar with the details.

Programmatic advertising can also allow advertisers to target their audience better. Programmatic can allow for better insights into the effectiveness of your campaign.
Header Bidding: A technique used in programmatic advertising to increase competition for ad inventory. This is the opportunity to get the best prices possible. Header bidding can make the bidding process more transparent.
Viewability: This metric measures whether an ad was actually seen by a viewer. Viewability is essential for ensuring that your ads are reaching their intended audience. The IAB has established standards for viewability, and this helps to ensure that ads are being measured correctly.
Ad Verification: The process of verifying the quality of ad inventory, to avoid fraud and ensure brand safety. Ad verification helps to maintain trust and protect your brand reputation. Ad verification is a critical part of a successful campaign.
